Cursor (SortedRecordset function)
<section begin=dpl_desc/><section end=dpl_desc/>
Cursor is a member of the SortedRecordset class.
Instantiates a RecordsetCursor object for a particular instance of a SortedRecordset object.
Syntax
%rscursor = %srecs:Cursor
Syntax terms
| %rscursor | A declared RecordsetCursor object, to which Cursor returns an instance of a RecordsetCursor object, if %srecs has at least one record. If %srecs has no records, Cursor returns a Null object. |
|---|---|
| %srecs | A reference to an instance of a SortedRecordset object. |
Usage Notes
- You can have as many cursors as you want for a record set.
- To test for an empty record set, use IsEmpty, which is much more efficient than testing the record Count for 0.
- The instantiated RecordsetCursor is automatically positioned on the first record in the set.
